About the role
Mill is a waste prevention technology company reimagining what it means to eliminate waste, starting with food. We build smart systems and infrastructure for homes, businesses, and municipalities that transform food scraps from landfill-bound waste into valuable resources, including chicken feed. Tens of thousands of Mill’s residential food recyclers are already helping households divert millions of pounds of food scraps every year, paving the way for our upcoming launch of Mill Commercial—the industry’s first end-to-end solution for managing, understanding, and preventing food waste in commercial environments (e.g. grocery, restaurants, food services). At Mill, we are passionate about building easy-to-use, beautifully designed technologies that keep food in the food system and out of landfills. We're seeking a Firmware Engineering Manager to lead the design, development, and implementation of low-level firmware for our next-generation connected product, while remaining hands-on as an individual contributor. You'll manage and grow a small team of firmware engineers while personally contributing to critical design and implementation work, working closely with cloud services, mobile app, product, and hardware teams to integrate connectivity features seamlessly. Key
Responsibilities People & Team Leadership Manage, mentor, and grow a team of firmware engineers, providing technical guidance, career development, and regular performance feedback. Set team priorities and roadmaps in partnership with product and hardware leadership, balancing technical debt, new feature work, and production readiness.
